Thermoelectric Generator Project

The Thermoelectric Generator is an experimental kit which demonstrates the direct conversion of heat into electrical energy using the Seebeck effect.The key component is the Peltier module that will be sandwiched between the two metal cans. As long as there is a substantial temperature differential between the two sides of the Peltier element, sufficient electricity will be generated to power the electric motor to turn the propeller.

Kit contents include:

(2) Metal Cans
23" Tie Strap
Thermal Grease
4" Propeller
DC Motor Round
Thermoelectric Generator
10" Velcro Hook & Loop Strips (must be cut to size)

You will also need:
Scissors
Hot & Cold Water

Begin by placing the cans face to face (notice yellow labels). Center the thermoelectric generator on one of the cans so that you can position and stick the hook & look strips to the cans.

Apply thermal grease like pictured so that when you sandwich the thermoelectric generator between the two cans, it will have thermal grease on both sides.

Connect the propeller to the motor shaft.

Cut a small piece of the hook strip to place on the side (opposite side of thermoelectric generator) of the "COLD" can. Cut another small piece of the loop strip to place behind the motor.

Remove the motor with propeller so that you can put the tie strap around the two cans to secure them with less difficulty.

Connect black motor wire with black thermoelectric generator wire. Connect red motor wire with red thermoelectric generator wire.

Pour in your cold water to fill up 75% of the "Cold" can and then pour hot water to fill up 75% of the "Hot" can.

Since the thermoelectric generator works from temperature differentials, using a glass alcohol thermometer, you can measure the temperature of both hot and cold liquids and see at which temperatures the propeller will start and then stop spinning . It may take a few minutes so record the time as well.
